The platform of a station 500 m long starts exactly where the last span of a bridge 1.7 km long ends. How long will a train 400 m long and travelling at the speed of 65 km/h take to cover the distance and the far end of the platform?
Answer & explanation
Correct answer: option 2
l__________________l____________i
1.7 Km (1700 m) 500 m
Total distance travelled = 1700 m + 500 m + 400 m = 2600 m
Time = \(\frac{2600}{65 × 5/18}\) = 144 seconds
